To all whom it may concern:

Be it known that I, CH LES HENRI Tonnnr, a subject of theBelgian King, and resident of Brussels, Belgium, have invented certain new and useful Improvements. in Filters, of which the following is, a speci fication.

This invention relates tofimprovements in filters of the type that are usually designated as domestic filters, and provides a filter which may be used either as a droprby-drop filter or as a pressure filter, and my invenion, consists of filtering members. each made up of; two or more sections of any suitable material that may be connected together by cement and through which water or liquid may percolate, slowly. or drop-bydrop without auxiliary pressure and more rapidly when; pressure is applied to the fluid to be. filtered, two sectionsot the filtering members providing a chamber that is closed except as to the outlet opening for the discharge of filtered water, the filtering members being lenticular or double convex as to configuration both as to the cavity and the exterior surface. The uppermost section of the filtering body is" saucer shaped, and the other section or sections are provided: with a centrally disposed opening and are each of identical shape.

My invention consists more particularly in the construction and arrangement of parts which, are assembled for coeoperation and comprise a receptacle which is. open at its upper part, the bottom having an aperture. and to. such bottom there is secured so as to be removable therefrom an annular section of a filtering body, the same being assp,ciated. with a closure that is saucer shaped the parts when o ned by cement or otherwise providing a hollow lenticnlar ,or v

double convex filter of stone-like material through which water willpercolate and be purified m r Several of; the annular saucer shaped filtering'units may be associated to form a column within a receptacle that is provided with a closure and an opening for filling the receptacle or for exerting upon the fluid in the receptacle pressure to add to the force of gravity and augment the percolation of the fluid contained in the receptacle through the hollow filtering units, as Will be hereinafter set forth an claimed In the accompanying. drawings which illustrate my invention; t Fig. 1 isa sectional elevation of a domest1c filter provided with a single filtering body; l I

Fig. is asection of afiltering rece tacle containing a vertical series of fil jering bodies.

The filter of my present invention is cornposed of an outer reservoir A (Fig; l) and an inner receptacle B, containing the water to. be filtered and within which. is. arranged a filtering body C of saucer-shaped, 01518 ticular shape, made of two parts. connected together a by 'means of suitable cement (Figs. 2 & 3) andin the center of thelower member or unit is an opening that is pro vided with a tube C extending through the bottom of the inner receptacleor container Band secured thereto by means of a screwnut G a washer C of India rubber or the like being provided to secure an air-tight connection. The bottom part of anouter vessel 'or container hasa partition that provides therein a reservoir A, which is provided with a tap A for the discharge of filtered water. The containerB" is suspended from the upper rim of the reservoirA by means of its annular shoulder 'O as shown in Fig, 1. and closed by means of a cover D, the central; portion o f which is strengthened by meansofa disk Ar ranged on said cover is yoke F having forked ends H, Hand carrying a set-screw G, the forks H, H of said yoke engaging apertures M, M (Fig. 6) prorided Iidfthe upper rim of the container B.

D and the Between the rm of the cover annular shoulder O of the container B I arrange an annular band or gasket of India rubber J. The cover D is provided with anipple K for the inlet of compressed air, and with a stopper or other device L for the inlet of other gaseous bodies as for instance carbonic gas under pressure, or for the admission of carbonic acid capsules or other pressure producing an H aerating substance.

My improved filter operates as follows: The water to be filtered is poured into the container B and the latter isprovlded with its cover D, upon which the yoke F is then placed so that the forked ends H, H

thereof engage the apertures M, M of the container B. Owinglto the fact that" the lower end of the set screw Gr engages a central notch of the disk E, the'yokeF will be securely held in place.

. Now if the set-screw G is screwed down,

the riin'ofthe cover D will be strongly pressed upon the rubber jointJ, whereby the container B will be closed' in an airtight way. I

Now Imay connect an air pump, for 1nstance a bicycle pump, to the inlet K, to compress air as desired below thecover D, or introduce a I suitable gaseous body through the inlet Ii, for the purpose of rapidly filtering and simultaneously aerating I the water contained in the container B, filtered and aerated from the tap A A 7 As shown in Fig. 7, two portions of filtering bodies'may'be connected at their bases water being discharged by means of cement, and this: connection' may be reinforced by. means of a metal tube section P held between two disks Rby flanging the rim portion at each :end of the tube isectionupon the corresponding washer R as shown. The filtering sections thus formed may be connected in series as shown in Fig. 8 for the urpose of providing a large filtering sur ace in a small space. Said series of filtering bodies C may be ar- 7 ranged within a container B tightly closed by means of a cover D capable of being connected to a water conduit. In this way I providean improved pressure filter.

I wish it to be understood that the details of construction of the filtersd'escribed and shown may be changed as desired with- .out departing from the scope of the invention.

vention, what I claim and desire to secure by LettersPatent, is: V I

1. In a domesticfilter, the combination with an outer reservoir and an inner containenof a filtering body of stone-like material of lenticular shape, arranged near the bottom of said container, a tube extending from the filtering body through the bottom of '7 Havingnow fullytdescribed said in-= the container, a means engaging the tube to clamp the filtering body to the container, a cover closing the top of the latter, and

means forpressing said cover upon the seat in order to make the container airtight.

2. In a domestic filter, the combinatlon with an outer reservoir and an inner container having an annular shoulder resting on the rim of said reservoir, of a hollow filtering body of stone-like material having a tube extending therefrom through the bottom of the container, a cover closing the top of the latter, an inlet for compressed air in said cover, a secondinlet forgaseous bodies insaid cover, and means for pressing the cover upon the annular shoulder of the container.

3. In a domestic filter, the combination .with an outer reservoir and an i'nner container having an annular shoulder' resting on the rim of said reservoir, of a filtering each of which is formed of two parts, connected together by means of cement, the

' lower sectlon of the lower filtering body being" provided with a tube for the discharge of filtered water, for the purpose setforth.

5. In a domestic filter, the combination with a water container, a. cover closing the top of the latter, and a waterjinletin said cover, of a vertical series of filtering bodies of elliptic or lenticular shape withinlsaid container, each body being formed of two N parts cemented'together said bodies being successively cemented together at, their bases and strengthened by means of tube sections and disks and a tube Extending from the lowermost filtering bodythrough the bottom of the container forthe dis-' charge of filtered water, substantially asset forth.

' In testimony whereof I have hereunto set my hand n presence of two witnesses.
